Cell–cell interaction refers to the direct interactions between cell surfaces that play a crucial role in the development and function of multicellular organisms. These interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is essential for the ...
Furthermore, as replication increases the amount of cells, the number of directions those cells can move without touching another is decreased. [22] Cells will also attempt to move away from another cell because they stick better to the area around them, a structure called the substratum, than on other cells. When the two cells colliding are ...
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
Gap junctions have continue to be found in nearly all healthy animal cells that touch each other. Techniques such as confocal microscopy allow more rapid surveys of large areas of tissue. Tissues that were traditionally considered to have isolated cells such as in bone were shown to have cells that were still connected with gap junctions ...
In biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes. Typically, the signaling process involves three components: the signal, the receptor, and the effector.
The nerve cells can be thought of as intermediary's, not so much communicating with each other but rather passing on the messages from one neighboring cell to another. Being "accessory" cells that pass on the message they require an additional space and can consume a lot of energy within an organism.

Invertebrates have several other types of specific junctions, for example septate junctions (a type of occluding junction) [4] or the C. elegans apical junction. In multicellular plants, the structural functions of cell junctions are instead provided for by cell walls. The analogues of communicative cell junctions in plants are called ...
